0.70 Update - Zwave Component Can't be setup, Can't Find Device

Configuration Z-Wave
1

Hello,

I use hass.io, not sure if this is more appropriate there.

I’ve been running hass.io on a RB3b for months, things work perfectly. I have a Z-wave mesh powered by an Aeotec Z-wave USB stick.

After update, it says the Z-Wave component could not be configured. Checking the logs says:

My zwave component has this defined USB path:

zwave:
usb_path: /dev/serial/by-id/usb-0658_0200-if00

Any advice would be greatly appreciated! Not sure what to do

Thanks!

check your usb_path and make sure it remained the same.

3

DId just get the same error to. After upgrading 0.70 and trying to add a new zwave device after. I have not edited any config file. Happened after i tried to add a new door lock today.

4

Same issue here. Also with another serial device (LaCrosse) I linked via /dev/serial/by-id, so it seems it’s not related to the Z-Wave component specifically.

5

Looks like this is happening with other serial devices I have the same issue with rflink and it looks like the rftx component is also having this problem.

Not sure what to do, at the moment I have downgraded back to 0.69.1

6

I think this is a docker bug you guys might want to hold off.

7

I have hass.io though

I wonder if it still affects me… I also got no errors updating to 0.70.

I guess I’ll just…wait…too lazy to downgrade to 0.69

**EDIT: ** So this was fixed by simply reverting the configuration.yaml to the standard setting and it worked. oh well, let’s hope the name sticks

What do you mean by this?

I just updated to 0.71 and got this zwave error

9

I did

claudio@ubuntu:~$ ls /dev/serial/by-id/
usb-0658_0200-if00

so did not change my configuration is still

zwave:
  usb_path: /dev/serial/by-id/usb-0658_0200-if00

but I do receive this error
